Specification texts: Wilo-Multivert MVI (1~3 V, EPDM, PN 16) Multistage, non self-priming, horizontal high-pressure centrifugal pump in in-line design. The pump shaft and the motor shaft of the IEC standard motor are connected by means of a clamp coupling. A separate lantern roller bearing ensures optimum admission of axial thrusts. Intermediate bearings in the hydraulics guarantee a long service life. The pump is suitable for water supply and pressure boosting, industrial recirculation systems, process water and cooling water circuits. It can also be used in fire extinguishing systems, washing systems as well as for irrigation. Special features/product advantages Corrosion-resistant impellers, diffusors and stage housings Drinking water approval for all components that come in contact with the fluid (EPDM version) Scope of delivery Wilo-MVI high-pressure multistage centrifugal pump Installation and operating instructions Counter-flange bolts, nuts and gaskets for optional round counter flanges Counter flanges of cast iron with the corresponding screws, nuts and gaskets for PN16 pump version with oval flanges Design notes Motor protection is to be provided on request or on site. Single-phase AC motor equipped with built-in thermal motor protection and capacitor The spacer coupling (from 15 kw) allows the mechanical seal to be replaced without removing the motor Counter flanges are available as accessories. Bypass sets are available as accessories.
